I'm almost embarassed to ask such a simple question but I'm pretty new to SQL and want to the do the following SQL select. I have two tables:
WORK ORDER HEADER DETAILS (WORKH) WorkOrderNumber | CustomerNumber | StartDate | EndDate
WORK ORDER LINES (WORKD) WorkOrderNo | Service
I want to select all customer numbers that have a work order that includes a line with the service code XXXXX and a start date of YYYYYY and end date of ZZZZZZ. Note that the first field in each table contains the same data but is named differently. It's this that's causing me a headache.
I just downloaded and installed Visual Basic Express Edition and SQL Server Express Edition. All I have in the Start menu is SQL Configuration Tools. My absolutely stupid question is, how do I get started with this?
I know a little bit about SQL from using SQL command line in Oracle, and I've built small databases before using Access. Where does this program fit into all of that? And what do I use and how can I get started with this program?
I'm a user interface designer working for a small development shop in a government agency. My boss feels it would help our team out if I learned a bit more programming (I'm on that already in VS2k8, VB.NET), and some general database theory and practical knowledge. The more I learn about programming, the more my utter ignorance of databases proves to be an obstacle. We use SQL2k5, so I've decided to cut my teeth on that; I don't have the free time to learn something simpler and then graduate to SQL, so it is what it is.
So, I'm looking for a "Dumb Even for a Dummy" guide to database fundamentals, with a strong emphasis on SQL in particular. I slogged through the first 30 pages of this forum and found a couple of MSDN resources but nothing stuck me as being basic enough. I'm hoping someone can provide me with some "Go here, newb" resources to get me started.
Can my program with SQL database run correctly on another com using win xp home edition, with only C# 2005 EE installed? Is it compulsory for every table in a database to have a primary key? Can I extract a data from a specific cell in a database table(click button get data)? How do I go about doing it (the simplest n straight forward method)?
Hello there... Pending receiving the full version from the higher powers at my work, I have downloaded the Evaluation version of SQL 2000, and set up an instance on my desktop machine. This was set up on an administrator account, and works fine. My main aim with SQL 2000 is to upsize all the companies piddling little Access 97 databases into an SQL backend and keep the 97 frontends. I have migrated some of the tablesets into SQL, and linked to them in Access 97 and they work fine. However, the problems are when I try and set up ODBC. When I enter ODBC as a different user on the server itself, the ODBC list of available SQL Servers shows me the correct server information - my PC ID no, followed by the server name. However, when I try and connect with another machine on the network, it only displays the PC ID no of the server, and not the server name. When I attempt to add the server with just the PC name, it doesnt find the server - same when I add the name of the database to the end of the PC ID no. I'm sure there is something really basic I have not done, but I'm totally stumped now. I am using Windows Auth, and have set up the login of the other PC I am trying to connect, as an authorised user. Please help me - I am just a doofus, please feel free to laugh at me...
I want to install SQLExp2K5 with Advanced Services on a standalone basis on my Dell Inspiron XPS laptop (Win XP sp2, .NET 2.0; 2gb RAM; 8mb broadband; hardware firewall/router) so that I can learn SQL/VB/VWD, and want to use SQL E 2K5 without internet connectivity (at least until I know what the hell I'm doing!)
Really confused as to what component(s), and services I should/should not install - so I've listed my questions below:
1. Service Account: As I'm not on / dont have a domain, i presume using a domain user account is not an option for me. Should I use the Local Service account ? If so, what are/can be the issues in doing so?
2. Authentication Mode: Is Windows Authentication the one to use for a standalone install?; how would I enable the "sa" account and set an "sa" password? In fact, do I even need an"sa" account / password for a standalone, non internet connected install?
3. Components at install: Is it OK to install all components first off?
4. IIS: Is it possible to install IIS and not allow it access to the internet (or is this a stupid question -bearing in mind I dont really know what IIS is/does)
5: Business Intelligence Development Suite: How do I add BIDS once (IF) I manage to install SQLExp2K5-Adv.Ser,?
6. SQLExp2K5 Books on-line: Am I right in thinking that I should install this after installing SQLExp2K5?
7: Visual Basic Express/Visual Web Developer Express: Do these need to be configured seperately to work with SQLExp2K5?
Sorry about the length of this post, but have tried to be as clear as possible. Also apologise in advance for silly/stupid questions :)
I have a query returning the Average of an Integer with a precision of zero. However because of this in my query and export I am only returning whole numbers for my Average.
Is there anyway in the query to modify the field for what I want to view so that it will return decimals?
I have a table of baseballTeams with columns baseballTeamName and a baseballTeamID
A have another table (baseballGames) which consists of baseball games which includes a homeTeamID and a visitingTeamID. Both of these columns are linked to the baseballTeamID from the baseballTeams table
I have been successful at joining the two tables and Selecting the baseballTeamName from the baseballTeams table for either the hometeam or visiting team as shown below:
SELECT gameID, homeTeamID, baseballTeamID,baseballTeamName FROM baseballGames, baseballTeams WHERE baseballGames.homeTeamID=baseballTeams.baseballTeamID
...but I cannot figure out how to select BOTH the homeTeam name and the visitingTeam name from the baseballTeam table
Hi - I feel stupied b/c I can't figure this out but I hope it's just a few seconds for some of the more senior posters of this forum: I have a table that looks like this: Table:RequestID: bigint... (a bunch of table specific columns)User_Status_ID: bigint (holds the bigint ID of the status table, below; always holds the ID to the most recent ID, if several)Provider_Status_ID: bigint (holds the bigint ID of the status table, below; always holds the ID to the most recent ID, if several) and then there is a second table that looks like this: Table: StatusID: bigintRequestID: bigint (the request ID, so I can see all status messages for the request)Time: TimestampCode: byte (there are only a few status messages) The status table holds both the status for users and providers, as they use exactly the same status code. What I'd like to get is a table/view that looks like this: RequestID:bigint (the request that this status belongs to)User_Code: byte (the code of th most recent user status)Provider_Code: byte (the code of the most recent provider status) Somehow, I am blanking how to create a query that returns both user and provider codes in one row. Any help greatly appreciated!!!!
I got this Error, Query Execution for Dataset 'Source'.
When i try to run a report that is actually a drillthrough from another report. It runs fine in Report Designer, and when i deploy to my Local server. But when i deploy it to my virtual Report Server, I get this error messege. Why is it doing this? and where can i see errors for this type of stuff, so i can figure this out. This uses the same Datasource as the report linked from it. That report works fine, why wont this one? any ideas?
Suppose we get two following tables: Table A: [USER_ID] [varchar] (11) NOT NULL , [COURSE_ID] [varchar] (11) NOT NULL , Table B: [COURSE_ID] [varchar] (11) NOT NULL , [COURSE_NAME] [varchar] (50) NOT NULL , [COURSE_NO] [varchar] (15) NULL , [BEGIN_DATE] [datetime] NULL , [END_DATE] [datetime] NULL , [CREATER] [varchar] (11) NOT NULL , and during the execution of my program, I can get the current use's id (USER_ID), say U0001. How can I retrieve the result set containing [COURSE_NAME], [COURSE_ID], but the current user's id (U0001) have Not been assigned in Table A. Thanks in advance. Ricky.
I'm not getting it. The query below "e.g." is exactly as I think it should be except for the <Join Clause> as there is only the match on site name. I tried joing on the site name, but only got the sites in the log. I want all the site names even if they don't have a log item for a given date range.
I'd post my real query if it would help, it's just that I'm chopping up some strings and converting some time stamps to dates as varchar for readability for the final report, which is an MSExcel pivot table.
My original post lies below.
TIA

Make log an outer join to site.
e.g
select s.name, l.ondate from site s RIGHT OUTER JOIN log l ON <Join Clause> where substring(id,3,6) in(select name from site) and ondate between getdate()-8 and getdate()-1
You didn't seem to have any logical join between the tables, but i'm sure you have, just put this in the <Join Clause>.
Oh, and read BoL, it helps no end.....

my 7 day query....
select s.name, l.ondate from site s, log l where substring(id,3,6) in(select name from site) and ondate between getdate()-8 and getdate()-1
This returns those sites that exist in the current log, however what I want is a result set that has a row for each name regardless if they are in the log.
I have 2 tables...

I am trouble getting the count of applications. In the below query MerApp.ApplicationID represents the applications. I'm trying to get a results of a count of applications for each sales team member.Before adding the COUNT() function. My query results show 3811 because it shows the sales team member numerous times because he has many applications with different IDs. For example sales team member A shows up in 75 rows because he has 75 different applications assigned to him.
SELECT (usr.FirstName + '' + usr.LastName)AS [Sales Team Member], MerApp.Assignedto, MerApp.ApplicationID, stm.UserID, MerApp.ActiveStatus FROM MerchantApplication MerApp INNER JOIN Users usr ON MerApp.assignedTo = usr.UserID INNER JOIN SalesTeamMembers stm ON usr.UserID = stm.UserID WHERE MerApp.ActiveStatus=1 GROUP BY MerApp.AssignedTo, usr.LastName, usr.FirstName, MerApp.ApplicationID, stm.UserID, MerApp.ActiveStatus
I want sales team member A to show up once with the count of applications to be 75 because that's how many are assigned to him.
This didn't work for me: SELECT (usr.FirstName + '' + usr.LastName)AS [Sales Team Member], MerApp.Assignedto, COUNT (MerApp.ApplicationID) AS [Applications], stm.UserID, MerApp.ActiveStatus FROM MerchantApplication MerApp INNER JOIN Users usr ON MerApp.assignedTo = usr.UserID INNER JOIN SalesTeamMembers stm ON usr.UserID = stm.UserID WHERE MerApp.ActiveStatus=1 GROUP BY MerApp.AssignedTo, usr.LastName, usr.FirstName, MerApp.ApplicationID, stm.UserID, MerApp.ActiveStatus
It didn't count the number of applications for each person.I have about 14 different sales team members. So I'm trying to have a query that produces 14 rows not 3811 rows
ARRRRRRRGGGGGHHHHH!!Please can you help, I'm going round the bend with this.I have a simple and small table called STOCKCATS, which I need to query toget back a dataset in a particular order, but although it looks simple Ican't get it to work. My table schema plus sample data to see the problemis as follows:DROP TABLE IF EXISTS `STOCKCATS`;CREATE TABLE `STOCKCATS` (`CATID` varchar(30) NOT NULL default '',`LEVEL` varchar(30) default NULL,PRIMARY KEY (`CATID`),KEY `indxCATEGORYID` (`CATID`));INSERT INTO `STOCKCATS` (`CATID`,`LEVEL`) VALUES('A001',''),('A002','A001'),('A003','A001'),('A004','A001'),('A005','A001'),('PCHW01',''),('MHW01',''),('FD01',''),('ELEC01',''),('MHW02','MHW01');INSERT INTO `STOCKCATS` (`CATID`,`LEVEL`) VALUES('MHW03','MHW01'),('MHW04','MHW01'),('MHW05','MHW01'),('PCHW02','PCHW01'),('PCHW03','PCHW01'),('PCHW04','PCHW01'),('PCHW05','PCHW01'),('PCSW01',''),('MSW01',''),('C001',''),('C002','C001'),('C003','C001'),('MV',''),('SUZ','MV'),('ALF','MV'),('PLASMA','ELEC01'),('T01','ELEC01'),('HEATING',''),('RAD','HEATING'),('P01',''),('B01','P01'),('BB','HEATING'),('FS','HEATING'),('WM','HEATING'),('AEROSOL',''),('SOLVENTS','AEROSOL'),('DGC','');INSERT INTO `STOCKCATS` (`CATID`,`LEVEL`) VALUES('DGXWINDOWS','DGC'),('DGXEXTRA','DGC'),('DGXCON','DGC');As you can see from the table structure, this table consists of 2 fieldvalues. The 1st is the category code and the 2nd is the level is at. If acatid has a level of nothing, eg '', then it means that it is a root levelcategory. If a catid has a another cat's catid in it's level, eg B01 hasP01, then it is a sub-category of this category, eg B01 is a sub-cat of P01.All I want to do is query this table and bring back the data so thatalphabetically it goes root level cat A1, then all the sub-cats for thisroot level, then root level A2, then all sub-cats for this root level and soon. An example using the above would be as follows:^ ^ A to G of root level cats plus their sub-cats....HEATING << root levelBB << sub-cat of heatingFS << sub-cat of heatingWM << sub-cat of heating/ / I to Z of root level cats plus their sub-cats....A few posters kindly gave me a solution of ORDER BY COALESCE(CATID,LEVEL),CATID and I thought this had done it, but I was looking at the ('A001',''),('A002','A001'), ('A003','A001'), ('A004','A001'), ('A005','A001')entries as these naturally fell into place. If you use this order commandon the above you will see that ('P01','') and it's associated ('B01','P01')sub-cat just don't come together.Does any body have any ideas?ThanksLaphan

Hi I am having two very basic problems which are very frustrating. I have read http://blogs.msdn.com/smartclientdata/archive/2005/08/26/456886.aspx and changed my DB to "Copy if newer" however when I use the connection string "|DataDirectory|MyDB.sdf" MyDB remains unchanged. (If I put the full path to MyDB in the connection string I will see the changes.) I have tried copying the DB file in the bindebug directory and opening the copy separately, and the changes still do not appear.
This leads me to my second issue. While trying to verify if the insert worked, I am trying to query the DB for the row I just inserted. I have found very little documentation describing how to do this; am I missing something/someplace obvious? Here is my code:
string strCommand = "SELECT * FROM Log WHERE Severity = @Sev AND Message = @Msg"; SqlCeResultSet resultSet = null; SqlCeCommand sqlCommand = new SqlCeCommand(strCommand, pConn);
resultSet always returns non-null, so I am clearly doing something wrong. Do I need to "read through" the resultSet to make sure there is something there? And if so, how? Should I be using a DataReader instead? (and if so how?) Am I going in the wrong direction? Just to be clear, I want to insert a row into my DB and then check that that row has been inserted by querying the DB.
Ok, I have a table that contains a number of columns, one of these columns contains a 'unitref' e.g.AC02/001D.
I import a new set of records, approx 7,000 per week in a DTS package from CSV Flat File into the table.
What I need to achieve at either the point of import of new data weekly, or once the new data is sitting in its final resting home, is a copy of the first two 2 Chars of the UnitRef, in the example above, this would make it 'AC' and then place that in a column named 'site_ref'.
Having posted the question on this forum relating to grabbing the first two chars of a value and placing them in a temporary table by utilising the Left(field,2) command in SQL (Kindly answered by CryptoKnight), I was wondering how I can do this possibly by using the inesrt into type command. I have many columns that get imported this is only a tiny step of many things that ideally would need to happen on an import,
How would I convert this query to ANSI 92 standard?
select p.InternalID, n.LastName from tblPatient p, tblName n where p.PatientID = n.EntID and n.EffDt = ( select max(n2.EffDt) from tblName n2 where n.EntID = n2.EntID and n2.EffDt <= getdate() )
Hi,I feel stupid for posting this question but I cannot find out how to create an SQL statement to return records that have been added today.My database table has a field called calldate which hold the date and time of the record added to the database i.e. "02/08/2005 16:55:41".Please can someone let me know how I can search to find all records added today. I thought it would be something like it, but I assume I need to format the calldate so it's just 02/08/2005.Select *From TableWhere CallDate = GetDate()ThanksBrett
I am having some difficulty writing a relatively basic query. The objective is to retrieve the new stories (headlines) for the past 3 days from the database. Since each headline can be assigned multiple categories (topics) the query returns a row for every headline assignment. I can't use the 'Group By' expression because one of the columns is nText.
So basically if there is an article written yesterday, "I Love Cats" that gets assigned both topics 'CATS' and 'PETS' I only it returned with the first topic assigned... 'CATS'. Here is a little image of the three tables being called:
http://64.225.154.232/temp_dbDiagram.gif
I don't think that this query is too difficult, but I'm just getting my feet wet with writing queries that are more than select * from whatever. Any insight or recommendations are greatly appreciated.
SELECT headline.HEADLINE_ID, headline.HEADLINE_TITLE, headline.HEADLINE_DATE, headline.HEADLINE_THUMBNAIL, topic.TOPIC_NAME, topic.TOPIC_URL FROM tbl_CCF_Headlines headline INNER JOIN tbl_CCF_Headlines_Topics ON headline.HEADLINE_ID = tbl_CCF_Headlines_Topics.HEADLINE_ID INNER JOIN tbl_CCF_Topics topic ON tbl_CCF_Headlines_Topics.TOPIC_ID = topic.TOPIC_ID WHERE (headline.HEADLINE_DATE IN (SELECT TOP 3 HEADLINE_DATE FROM tbl_CCF_HEADLINES GROUP BY HEADLINE_DATE ORDER BY HEADLINE_DATE DESC)) ORDER BY headline.HEADLINE_DATE DESC
Does anyone know how I can get just one record returned from a select statement - not by doing set rowcount, but saying I want, for example the third record returned.
I'm trying to do a stored procedure that does a select of current records that will reduce the output to roughly 24 records and then get a random record from this - I need to do it all in a stored procedure.
What I have so far is :
BEGIN DECLARE @Count int DECLARE @RowCount int DECLARE @IDint
/* Randomise the Data */ SELECT @Count = Count(*) FROM MyTable WHERE fRotation = 1
SELECT @ID = Rand() * @Count
END
As you can see, @ID will hold a record no.
I cant use batch cursors as they are giving me problems - work for a short while and then they mess up.
I create the cube and KPI successfully.Now want to define the "trend" in MDX.the problem is the trend is not linear, but a quadradic function, which means the kpi target is the highest point in the function.in order to get the "trend expression", to get the "absolute value" is needed (as to measure how near to the target point).but i browsed the operators available, there is no ||.
Seems to me like microsoft mentions learning, but it's never for beginners. I haven't found a single tutorial that says how to make a simple database step by step.
Does anybody know about a tutorial focused on teaching the very basics (a kind of "hello world" application) from setting up the new database with a few sample fields to "deploying" it (making it ready to be used)?
Please let me know.
Once I'm through with these first steps there seems to be a lot of helpful learning resources meant for experienced and expert users, but I'm not there yet...
I have a table that expands and pushes down objects under it, i don't want this to happen i want my objects to use an absolute position so i can jiggle things how i want them - this doesn't seem to be an option in SSRS 2005?
when i put a table beside 2 graphs on my report, as the table expands it pushs the bottom table down ONLY when when it's displayed on the final webpage. the preview features shows it as being correct.
how do i prevent the expanding table from pushing the tables BESIDE it down? i could understand if it was a table below it, but it's not.
Hi all, I have a strange situation. I have a field in the database that has to be a string type field of around 4000 characters.
So naturally I setup the field as type: varchar length: 4000
However when I try to put any text in this field I find that I can put no more than 1023 characters of ascii text in there.
To check if this was a max record length prob I setup a test table with only 2 fields: ID: int, PK, Identity longVarchar: varchar, 4000
and tried to put some ascii text into the field called longVarchar. Again the most I could put in was 1023 characters!
Thinking that it could just be that SQL svr box that was wacky, I tried it on another one with the same result.
I have tried using other field types (nvarchar, char) and have found that they all could only hold 1023 characters max, no matter what how high I defined the size of the field.
Try it out yourselves and see if you get the same result. Any useful suggestions would really be appreciated.
Have a bit of an SQL challenge in that I need to create a well performing view in SQL2008R2 which calculates hours remaining at any given point in time. This is not a simple sum but has some absolute values included.

I have a report that prints cards for customers. The body of the report contains an address box, letter body, followed by a table that contains all the people to be printed on the cards. If the number exceeds 6 people, another page is to be printed, with no address or letter body, but the table with the remainder of the people on it.
I have been able to get everything to work except for the location of the table on the subsequent pages. They do not appear at the bottom as they do on the first page, but at the top of the page. I've tried using a rectangle as a container for the table, with no luck.
I seem to remember doing this in the past, but as projects get shelved for an extended period of time, the technical knowledge tends to fade.
Any suggestions would be greatly appreciated. Thanks
We are facing some issues with SSIS and thought if you could be of some help.
Actually, instead of Deploying our SSIS projects we copy the SSIS files to a different server from where we execute the SSIS Packages. The reason being, we have a Core Version of the application and this is deployed to different markets and subsequent customisations are performed in the market specific version of the Packages. The problem is although we have a Package Configuration Xml File for our Connection object, the first time when we copy the Packages, we have to manually open each of the Package and change the URL of the Xml File for Configuration. I read through some of the articles on the internet and came to know that the Package Configuration does not support relative path and only absolute path is possible.
Can you please share some of your suggestions on the above problem.
